C#RealProxy:泛型方法?

有一个很好的 MSDN article 关于RealProxy我建议你阅读。 MethodCallMessageWrapper 这就省去了你直接对付 Properties 字典。从后者你可以得到 MethodBase ,它又包含泛型参数:

internal class MyProxy : RealProxy
{
   private object m_instance;    
   private MyProxy( object instance ) : base( typeof( IFactory) )
   {
      m_instance = instance;
   }

  public override IMessage Invoke( IMessage message )
  {
     IMethodCallMessage methodMessage =
        new MethodCallMessageWrapper( (IMethodCallMessage) message );

     // Obtain the actual method definition that is being called.
     MethodBase method = methodMessage.MethodBase;

     Type[] genericArgs = method.GetGenericArguments(); //This is what you want

     return new ReturnMessage(...);
  }

  ...
}

IMessage 参数应该是 IMethodMessage MethodBase 属性:

public override IMessage Invoke(IMessage message)
{
    IMethodMessage methodMessage = message as IMethodMessage;
    if (methodMessage != null)
    {
         MethodBase method = methodMessage.MethodBase;
         Type[] genericArgs = method.GetGenericArguments();

         ...
    }
    else
    {
        // not a method call
    }
}
